Gavagai: fantasy word from a thought experiment of W.V.O. Quine. An expression (or fragment) of a completely foreign language is not unambiguously translatable into a known language, because it is not determined, whereupon the expression of the foreign language relates. Even pointing to an object does not create unambiguity. E.g. only a part or a property of the object can be referred to. See also translation, indeterminacy, translation manual, analytical hypothesis, uncertainty, reference, meaning._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.
